Benefits and Risks CRT-D DEVICES and CRT-P DEVICES

Risks of Getting a CRT Device

Cardiac resynchronisation therapy, or CRT, is a heart failure treatment option for some heart failure patients. An implantable heart device sends tiny electrical impulses to the lower chambers (ventricles) of the heart to make them beat together again in a more synchronised pattern. This improves the heart’s ability to pump blood and oxygen to the body.


It is not a replacement for drug therapy, and it is recommended that cardiac resynchronisation therapy patients also continue taking medication as determined by their physician.


Risks associated with these implantable device systems include, but are not limited to, infection at the surgical site and/or sensitivity to the device material, failure to deliver therapy when it is needed, or receiving extra therapy when it is not needed.

After receiving a CRT device, you will have limitations with respect to magnetic and electromagnetic radiation, electric or gas-powered appliances, and tools with which you are allowed to be in contact.

Treatment with these implantable device systems is prescribed by your doctor. This treatment is not for everyone. Please talk to your doctor to see if it is right for you.

Your doctor should discuss all potential benefits and risks with you. Although many individuals benefit from the use of this treatment, results may vary.
